ahh, okay, so maybe I should try swapping out fuel pump?

yeah when cold, 1st drive of the day, it runs fine, then lets say, i will put it at rest for an hour, come back, start it up, and its going to run like a pig, choke on it self, for like 1min or 2, but when I just keep revving it, and put my foot down, does not really do much, for 1st few second, and the it just goes...

Think it through....

And I’ll give you a clue to help, a failing fuel pump usually gives less pressure than needed and not more....!

You’ve, possibly, already got more petrol than you need.

Just guessing and replacing things is an expensive way of making little or no progress
To assess the system here you need to actually check fuel pressures, check condition of components and sensors and read what’s coming out of the exhaust.
I don’t know the NG setup well enough to advise remotely I’m afraid

This will be useful

MSH could pick a fight in an empty room but he’d a good idea of what he was on about
